在 Golang + mongodb 中输入时间字段

Question

我有结构：

type TripFeedback struct {
    ID        primitive.ObjectID `json:"_id" bson:"_id,omitempty"`
    UserID    string             `json:"user_id" bson:"user_id"`
    WaybillID uint64             `json:"waybill_id" bson:"waybill_id"`
    Rating    Rating             `json:"rating" bson:"rating"`
    Comment   string             `json:"comment" bson:"comment"`
    CreatedAt time.Time          `json:"created_at" bson:"created_at"`
}

当我创建一个对象时，它看起来像这样（看时间）：

0: {ObjectID("010000000000000000000000") 53566444-4334-11ee-be56-0242ac120002 5 4  2023-08-25 13:44:22.89 +0000 UTC}
1: {ObjectID("020000000000000000000000") 53566444-4334-11ee-be56-0242ac120002 12 4  2023-08-25 13:44:22.89 +0000 UTC}
2: {ObjectID("030000000000000000000000") 53566444-4334-11ee-be56-0242ac120002 51 3  2023-08-25 13:44:22.89 +0000 UTC}
3: {ObjectID("040000000000000000000000") 53566444-4334-11ee-be56-0242ac120002 53 5  2023-08-25 13:44:22.89 +0000 UTC}
4: {ObjectID("050000000000000000000000") 53566444-4334-11ee-be56-0242ac120002 53 5  2023-08-25 13:44:22.89 +0000 UTC}
5: {ObjectID("060000000000000000000000") 53566444-4334-11ee-be56-0242ac120002 54 4  2023-08-25 13:44:22.89 +0000 UTC}

但是当我从 mongodb 收到响应并将其解析为相同的结构时，它看起来像这样：

0: {ObjectID("010000000000000000000000") 53566444-4334-11ee-be56-0242ac120002 5 4  2023-08-25 13:44:22.8902373 +0000 UTC m=+0.005347601}
1: {ObjectID("020000000000000000000000") 53566444-4334-11ee-be56-0242ac120002 12 4  2023-08-25 13:44:22.8902373 +0000 UTC m=+0.005347601}
2: {ObjectID("030000000000000000000000") 53566444-4334-11ee-be56-0242ac120002 51 3  2023-08-25 13:44:22.8902373 +0000 UTC m=+0.005347601}
3: {ObjectID("040000000000000000000000") 53566444-4334-11ee-be56-0242ac120002 53 5  2023-08-25 13:44:22.8902373 +0000 UTC m=+0.005347601}
4: {ObjectID("050000000000000000000000") 53566444-4334-11ee-be56-0242ac120002 53 5  2023-08-25 13:44:22.8902373 +0000 UTC m=+0.005347601}
5: {ObjectID("060000000000000000000000") 53566444-4334-11ee-be56-0242ac120002 54 4  2023-08-25 13:44:22.8902373 +0000 UTC m=+0.005347601}

为什么时间字段不同？怎么处理呢？我的

CreatedAt

不应该是

time.Time

类型吗？（因为至少我必须编写一些测试）。谢谢你

Answer 1

数值相同，可以忽略

m=

部分。

TripFeedback.CreatedAt

属于

time.Time

类型，它不能是任何其他类型，因为 Go 是静态类型语言。
